Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.

* Name: fhex2mem
|
|
*
|
|
* Description:
|
|
* Read the Intel HEX ASCII data provided on the standard stream
|
|
* 'instream' and write the binary to memory.
|
|
*
|
|
* If, for example, instream is stdin, then the HEX ASCII data would be
|
|
* taken from the console and written to memory.
|
|
*
|
|
* Input Parameters:
|
|
* instream - The incoming standard stream from which Intel HEX data
|
|
* will be received.
|
|
* baseaddr - The base address of the memory region stream.
|
|
* endpaddr - The end address (plus 1) of the memory region.
|
|
* swap - Controls byte ordering. See enum hex2bin_swap_e for
|
|
* description of the values.
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) is returned on success; a negated errno value is returned on
|
|
* failure.
|
|
*
